a)
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land
mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically
with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic
side survey should be considered. If the measured field strength outside the location in which the MYSIGN S
is used exceeds the compliance level, the MYSIGN S should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as relocating or using
another location of the MYSIGN S.
b)
Over the frequency range from 150 kHz to 80 MHz the field strength should be lower than 6 V/m.

Recommended separation distances between portable and mobile RF communication equipment and
the MYSIGN S
The MYSIGN S is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of the MYSIGN S can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment (transmitters)
and the MYSIGN S as recommended below, according to the maximum output power of the communications
equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d
in meters (m) can be estimated using the equation applicable to the frequency of the transmitter, where P is
the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer.
